Changes in the social situation and the high economic growth in Formosa have been making the life of people richer, leading to a bewildering change in their life style. In this study, we aimed at grasping the actual living conditions of some Formosan pupils, together with correlation of their dietary life to their living habits. The following results were obtained. 1) The physique judgment by the Rohrer's Index revealed the prevalence of obesity in 12.1 and 6.7% of elementary school male and female pupils, respectively. 2) The family consisted of 5.0 f 1.5 members for the former school pupils, respectively, and two generations household was noted for 75.1%, respectively, indicating a transition to the nuclear family. 3) The habit of lack of a meal was noted to be as high as 12.2%, respectively. Lack of appetite and no time enough for eating were predominant reasons. 4) The frequency of taking meals with all the family was as high as 92.5% for dinner and as low as 4.9% for breakfest, respectively, enabling us to get a glimpse of the Formosan dietary habit. Pupils in a situation such that a child takes meals alone represented 25.5%, respectively, indicating an increasing tendency with advanced grade. 5) In terms of the dining-out habit, ca. 12.0% of the former school pupils had a habit of dining-out every meal, which was markedly composed of staple food such as noodle and bread. 6) In terms of the meal-taking frequency by food group, former school pupils showed a higher frequency of taking rice, bread, meat, processed meat, fruits, vegetables, eggs, milk and fat, suggesting a dietary tendency to the European style. 7) As to the result of factor analysis, two factors were extracted from both male and female, cumulative contribution rate accounted for 86.6 and 85.6% of the variance and revealed a fairly similar dietary pattern for the former school pupils. 8) In terms of overall healthiness judgment, as low as 18.8%, were judged healthy, compared with as high as 37.8%, judged unhealthy respectively, with no sex difference being observed.
